Explain briefly work energy and power

Work can be defined as transfer of energy.

Energy can be defined as the capacity for doing work

Power is the work done in a unit of time.

Explanation:

Work can be defined as transfer of energy. In physics we say that work is done on an object when you transfer energy to that object.

Power is the work done in a unit of time. In other words, power is a measure of how quickly work can be done.

Energy can be defined as the capacity for doing work. The simplest case of mechanical work is when an object is standing still and we force it to move
